Ryu and Foulu have the ability to change into dragons using their "Meditation" skill. Both Ryu and Foulu have different ways to achieve this.

New Meditation dragon forms can be acquired by touching dragon gems (shiny, colorful, crystal-like ovals), which are found in some locations. Some dragon forms, such as Aura, Astral, Kaiser and Tyrant, are acquired automatically after a certain game event.

Some of the dragons can evolve into more powerful forms once. This happens when you have enough game points to do so. Not all of the dragon forms grow stronger, though. Only the Wyvern (into Weyr), Behemoth (into Mammoth), Myrmidon (into Knight), Mutant (into Punk) and Serpent (into Peist) actually change forms. Of course, you need a lot of game points for these evolutions. Game points can be acquired from mini-games such as the wild water rafting on Mount Ryft and the fishing game.
